If you use <ant> or <antcall> and if the "copy.compile.post" macro
contains text or attributes that have embedded properties (like "${name}")
which may change when the a new project is used, the macro
contents will be different and the ant core code will whine about
a change to the macro.

There is a bug report about this (cannot remember the number) from
a netbeans developer.
